CONSTRUCTION OF FLOORING AND CEILING.

SPECIFICATION forming part of Letters Patent No. 259,577, dated June 13, 1882.

Application filed December 29, 1881.

To all whom it may concern:

Be it known that I, GOTFRIED L. NORRMAN, of Atlanta, Georgia, have invented a new and useful Construction of Flooring and Ceiling; and I hereby declare the following to be a full, clear, and exact description thereof, reference being bad to the accompanying drawings, making part of this specification, in which- Figure l is a vertical section through the floor and ceiling. Fig. 2 is a vertical section through the flooring and ceiling on a line 00 00 at right angles to the line of Fig. 1.

The object of my invention is to mold the space heretofore existing between the ceiling and the floor above in the construction of houses, and produce a cheap, economic, ratproof, and substantially tire-proof ceiling and floor; and my invention consists in the certain combination and arrangement of wood or iron girders, planking, furring, lathing, and plas tering, as is hereinafterfull y described and specifically claimed.

In order that those skilled in the art may make and use my invention, I will proceed to describe the manner in which I have carried it out.

In the said drawings, A A are wooden or iron girders, placed, say, from eight to twelve feet apart. At right angles to and directly upon these girders I lay heavy planking B, of two or more inches in thickness, and upon this main floor B, I preferably lay a top floor, G, of lighter material-such as ordinary tongued and grooved yellow-pine flooring .or tiling-which (No model.)

gives a proper finish to the floor. On the lower 5 side of the main flooring B, I nail at proper distances farting-strips D I), and to these I fasten the laths E to receive the plastering F. By this construction I am enabled to nail the laths on the furring one inch apart, so as to 0 gain the great advantage of having much larger keys to the plastering between the laths than is usual, and thereby greatly lessen the danger of dampness, sweating the laths, and breaking the keys of the plastering, and its consequent falling. The shallow depth of the furring enables me to press the mortar against the flooring, so as to make the whole construction solid, and, the floor and ceiling being substantially a solid mass, there are no interior spaces, as between ordinaryjoists, for tire or rats to pass. The girders can be ornamented in any desirable manner.

It is evident that but one layer of plank may be used upon the girders, or that more than two layers may be used, without departing from the spirit of my invention.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

The composite floor and ceiling consisting of the flooring-planks, furring-strips D, laths E, plastering F, and supporting-girders A A, all constructed and arranged as set forth.
